Ann, yes, having two accounts does affect what happens here. Proboards gets confused when you have two accounts. It's better just to have one. I delete all the student accounts on the class forum once the class is over. My answer above is the correct one for fixing the problem.
However, this was written for students taking one of our classes and shows you directly uploading to the site. You can't do that here because we don't have enough storage space.
If you would like to email me photos, I will be glad to upload them to our WordPress site and then send you a URL so that you can use that to post photos.
You can set up a WordPress site for free, upload photos to it and then share from there. You can make your WordPress site private so no one can see it and just use it for storage. I would suggest making sure that your photos are resized before uploading them to any site.
